Name of the Vulnerable Software and Affected Versions Firefly III versions prior to 4.7.17.3

Description The issue arises from a lack of filtration of user-supplied data in image file names, leading to stored XSS. The JavaScript code is executed during attachments/edit/$file id$ attachment editing. It is noted that an attacker must have the same access rights as the user to execute the vulnerability.

Recommendations For versions prior to 4.7.17.3, update to version 4.7.17.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the attachments/edit/$file id$ endpoint to minimize the risk of exploitation. Avoid using user-supplied data in image file names until the issue is resolved.
